Ratios are basically:

for this much of this:theres this much of that

lets say you have 4:1 in spoons and forks.

for every 4 spoons, there is 1 fork. if there is 8 spoons there are 2 forks and so on.

The percent is 400%

if you meant 1:4 the percent would be 25%. all other rules apply.

for every 1 spoon you have 4 forks.

Question

99 Points Need Help! How to reflect over y= -x+6

Solution 1

To reflect in the line y = -x + 6, we translate everything down 6 first. This will make it seem like we are reflecting in the line y = -x

(x,y) → (x, y-6)

Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative

(x,y) → (-(y-6), -x)

Then we move everything back up again

(x,y) → (-(y-6), -x + 6)

I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.

(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)

You should graph this out to confirm with the reflection line.

(x,y) → (x, y-6)

Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative

(x,y) → (-(y-6), -x)

Then we move everything back up again

(x,y) → (-(y-6), -x + 6)

I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.

(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)

You should graph this out to confirm with the reflection line.

Solution 2

** (x,y) → (-(y-6), -x + 6) **

Question

Please Help!!!!!! So i know how to reflect over line y=-x but how would i do it over line y=-x+6. An example would be helpful and a rule for more problems of this kind.

Solution 1

(x,y) → (x, y-6)

Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative

(x,y) → (-(y-6), -x)

Then we move everything back up again

(x,y) → (-(y-6), -x + 6)

I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.

(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)

You should graph this out to confirm with the reflection line.

Question

PLEASE!!! I NEED THIS ANSWER DESPERATELY Data is collected for the average april temperature and degree of latitude The line of best bit for the data is found where L is the degree of latitude and T is the temperature in degrees Fahrenheit
T = -7/6I + 84
Predict the temperature at a latitude of 60

Solution 1

The answer to this question is 14 degrees Fahrenheit.

T(60) = (-7/6)(60) + 84 = 14

T(60) = (-7/6)(60) + 84 = 14

Solution 2

The answe is 14 I hope I helped

Question

(3n-1)(3n+2)
...anyone know this?...

Solution 1

The answer to this question is 9n^2+3n-2. We expand this polynomial factored with the distributive property

(3n-1)(3n+2) = 3n(3n-1)+2(3n-1) = 9n^2 - 3n + 6n - 2 = 9n^2 + 3n - 2

(3n-1)(3n+2) = 3n(3n-1)+2(3n-1) = 9n^2 - 3n + 6n - 2 = 9n^2 + 3n - 2

Solution 2

The first step for solving this expression is to multiply each term in the first parenthesis by each term in the second parenthesis (FOIL method)

3n × 3n + 3n × 2 - 3n - 2

Calculate the product of the first two numbers.

9n² + 3n × 2 - 3n - 2

Calculate the product of the next set of multiplication.

9n² + 6n - 3n - 2

Collect the like terms that have a variable of n to get your final answer.

9n² + 3n - 2

This means that the correct answer to your question is going to be 9n² + 3n - 2.

Let me know if you have any further questions.

Solution 1

Well it is gonna be compressed inward and down 6 post the graph

Question

A video game was $38. This weekend the game will be marked 13 percent off. How much is the game this weekend?

Solution 1

Discount = 13% x $38 = 0.13 x 38 = $4.94

Cost of the game after discount = $38 - $4.94 = $33.06

**Answer: $33.06**

Cost of the game after discount = $38 - $4.94 = $33.06

Question

Jade is making a square birthday card and she's going to put a ribbon borders on each of the 4 equal sides piece of ribbon that is 33 inches long do you have all of the ribbon how many inches of ribbon conget put on all equals side

Solution 1

8 inches can cover each side

(she will have 1 inch left)

(she will have 1 inch left)

Question

How many cubic feet of water can a 18 inch by 19 inch by 36 inch aquarium hold?

Solution 1

Volume = Length x Width x Height

Volume = 18 x 19 x 36 = 12312 in³

**Answer: 12312 in³**

Volume = 18 x 19 x 36 = 12312 in³

Solution 2

ft.

Question

Find the volume of a right prism with height h=10 cm, if the base is a trapezoid with height htr = 3 cm and bases of 2 cm and 5cm

Solution 1

We have been given that the base of the prism is a trapezoid. Hence, first of all we find the area of the trapezoid.

Trapezoid has height 3 cm and bases of 2 cm and 5 cm.

Hence, the area of the trapezoid is given by

Therefore, the volume of the right prism with height h=10 cm is given by

**Therefore, the volume of the right prism is 105 cubic centimeters.**

Solution 2

Area of the base = 1/2 x 3 x ( 2 + 5 ) = 10.5 cm²

Volume =10.5 x 10 = 105 cm³

**Answer: 105 cm³**

Volume =10.5 x 10 = 105 cm³

Question
